Twitter user @EverglowAnn recorded a moment where Niall, 23, walked by Zayn, 23, and they shook hands as he passed by. The moment appears a bit awkward, which you can see for yourself in the video below.

The 18-year-old singer invited Niall, 23, backstage at the 2016 American Music Awards to perform a special duet rendition of his hit song “Mercy,” which he performed on stage along with “Treat You Better” that same evening.

The former One Direction singer performed his debut solo single “This Town” at the event, backed up by a pianist, a drummer, a cellist and a backup guitarist.

“You always get nervous before these kind of things. When it’s your own gig, you can get away with it a little bit more. The whole crowd comes to see you, so you can kind of get away with a bit more messing about,” Niall shared.

He added, “But when it’s this kind of thing, you get nervous—it’s live TV.”
